I have a few e-books I'm thinking of trying to sell through unique affiliate links. Each one sells for different prices, ranging around $10 each. Commissions are 50%, so can I expect any decent income getting around $5/sale?
Will people buy them? Have you done any market research? Who knows what you can do? The amount of the commission is not relevant. What is relevant is if there is demand for the product, how large is the market, and how much of the market can you capture. Grocery Stores sell a ton of $10 items.
